Consideration was paid in cash upon closing with funds borrowed from the secured credit facility. During September 2014, in a non-brokered registered direct offering, which units are subject to certain transfer restrictions, Ferrellgas issued to Ferrell Companies Inc. and the former equity holders of C&E sellers, an aggregate of 1.5 million common units for an aggregate purchase price of $42.0 million.
